Special attention is paid to the design and nanoparticle formulation of these so‐called smart drug‐delivery systems. Dual stimuli‐responsive nanoparticles capable of fine‐tuning drug release to augment therapeutic efficacy have become a promising tool for anticancer drug delivery. However, the rational design of these “smart” nanoparticles for a selective delivery and controlled release of multidrug combinations in cancer cells to achieve synergistic effects remain challenging. Key words: nanoparticles, stimuli-responsive, tumor microenvironment, diagnosis, theranostics, clinical translation Introduction Since the discovery of the enhanced permeability and retention (EPR) effect and impaired lymphatic drainage of tumors [1], nanocarriers have been regarded as promising drug delivery vehicles to The stimuli-responsive nanoparticles can respond to different stimuli at corresponding times and locations to deliver and release their drugs and associated therapeutic effects. Moreover, the spatial distribution of nanoparticles within the combined material can be varied by exposure to heat or light, creating a new route to stimuli-responsive materials. 2013-05-01 · To this end, various “intelligent” polymeric nanoparticles that release drugs in response to an internal or external stimulus such as pH, redox, temperature, magnetic and light have been actively pursued.
Moreover, the nano-sized pores in the outer shell of these nanoparticles can be harnessed to construct stimuli-responsive nano-valves. These valves could be 23 000 € Smart mesoporous silica nanoparticles with stimuli-responsive surface functions as bisphosphonate drug and siRNA delivery carriers towards tumor prototypes that actively target and deliver nanoparticles (NPs) into the tumour tissue where a stimuli-responsive mechanism releases the anti-tumor drug(s). NanotechnologyBiosensorsEmerging Concepts in Analysis and Applications of comprehensive review on stimuli-responsive hydrogels and their diverse.

After entering a targeted cell through endocytosis, nanoparticles undergo Oct 23, 2013 These include liposomes, polymer nanoparticles, micelles, dendrimers, and inorganic nanoparticles made of iron oxide, quantum dots, gold or This thesis mainly focuses on the development of stimuli responsive nanoparticles for cancer targeted therapy. These nanoparticles either response to internal Recent advances in synthesis and fabrication of stimuli-responsive polymeric nanoparticles with built-in stimuli-responsive components (Part A) and surface Stimuli-responsive nanoparticles as emerging controlled drug release systems. The stimuli are applied as following: application of an external stimulus such as Jun 4, 2020 The rapid development of nanotechnology results in the emergence of nanomedicines, but the effective delivery of drugs to tumor sites remains Dr. Makhlouf is the editor of 13 books, 20 book chapters and over 180 articles.

Recent advances in synthesis and fabrication of stimuli‐responsive polymeric nanoparticles with built‐in stimuli‐responsive components (Part A) and surface modifications of functional nanoparticles that facilitate responsiveness (Part B) are outlined here. These stimuli-responsive nanoparticles have demonstrated, though to varying degrees, improved in vitro and/or in vivo drug release profiles. In an effort to further improve drug release performances, novel dual and multi-stimuli responsive polymeric nanoparticles that respond to a combination of two or more signals such as pH/temperature, pH/redox, pH/magnetic field, temperature/reduction, double pH, pH and diols, temperature/magnetic field, temperature/enzyme, temperature/pH/redox The thermo-responsiveness and singlet oxygen generation of the loaded ICG in DMMA-modified PLL nanoparticles are comparable to those of free ICG under laser irradiation, which induces higher cytotoxicity to cancer cells compared to succinic anhydride (SA)-modified PLL nanoparticles that are not pH-responsive.
Such systems are able to control drug release by reacting to naturally occurring or external applied stimuli. Special attention is paid to the design and nanoparticle formulation of these so‐called smart drug‐delivery systems. Dual stimuli‐responsive nanoparticles capable of fine‐tuning drug release to augment therapeutic efficacy have become a promising tool for anticancer drug delivery.

Stimuli-responsive nanoparticles have been designed and studied, exploring their potentiality as self-assembled materials as building blocks for the development of "smart" materials for bio-applications. Perylene diimide derivatives (PDI) have been used as fluorogenic units and structural components of assembled high-brightness nanoparticles, where fluorescence changes can be triggered by Dual stimuli‐responsive nanoparticles capable of fine‐tuning drug release to augment therapeutic efficacy have become a promising tool for anticancer drug delivery.

4. Gases. As we have seen so far, reversible, stimuli-responsive self-assembly. of nanoparticles typically relies on the formation of noncovalent. Stimuli responsive nanoparticles systems are divided into 2 classes: internal (pH, enzyme, ROS, hypoxia, redox) and external (radiation, electromagnetic, thermal) stimuli depending upon the method of inducing the delivery of the drug (Figure 1) (Taghizadeh et al., 2015; Yao et al., 2016). 2016-03-23 · Here we report the development of stimuli-responsive clustered nanoparticles to systematically overcome these multiple barriers to cancer chemotherapy.
